"The overall teen birth rate rose slightly in 2006 after steadily declining since 1991, according to the latest figures from the Centers for Disease Control and Prevention. The report shows the birth rate for teenagers ages 15-19 rose 3 percent between 2005 and 2006.

That translates to 41.9 births per 1,000 in 2006, a decline of 34 percent from the all-time high of 61.8 births per 1,000 in 1991."It's way too early to know if this is the start of a new trend," Stephanie Ventura, head of the Reproductive Statistics Branch at CDC, said in a prepared statement. "But given the long-term progress we've witnessed, this change is notable."
